Shipped with Leopard and had a seamless upgrade to Snow Leopard.ĭid I say it's fast! Handles multimedia tasks with ease and even equals or bests my much newer Win 7 Pro 64-bit PC. Whisper quiet, and much more so than my Powermac G5 dual 2.5ghz and any Win PC I've ever owned.Ĭompatible with a boatload of software, and no preference for Universal or Intel only SW. It shipped with two 2.66ghz dual core Xeons (Quad core), 4 gigs of FB-DDR2 (8 x 512mb) and Nvidia 7300 GT 256mb video card. Purchased this used and its proven to be a great buy. There's still plenty of tread on these tires even as the machine moves on from the Applecare years to year 4 and hopefully many more to come. The options this Mac Pro gives you really make it a strong contender if you're looking for something that's a little cheaper than the brand new models. I just added a new SSD drive to the mix to be my start up drive and am pleased with the new speed. The great thing is you can add more RAM or faster/more hard drives to give these machines more life. You can't get that functionality from an iMac (even a brnad new Core i7 one)and that's one of the reasons I like this machine so much - its expandability. I also added a CompressHD Matrox card to speed up h.264 compression. I added a Matrox MX02 card to use this Mac Pro as an injest station for video production. I have installed a Sata card from OWC to use the extra Sata ports on the motherboard. I'm using my 2-2.66GHz Dual core Mac Pro as a second machine for rendering and doing some other crunching while I keep working on my main 2-2.8GHz Quad core Mac Pro. If you must have the newest and fastest these aren't for you. You can get something that's much faster, but these 1st gen Mac Pro's can still pull their considerable weight (40+ lbs). EEK! 3+ years old in computer terms is ancient. These machines are getting up there in age. I am a happy owner of the Dual Processor 2.66 Dual Core 1st generation Mac Pro (1,1).
